Abstract

L'invention concerne d'une manière générale un procédé et un système permettant de déterminer la position et l'alignement d'un plan par rapport à un axe d'intersection et l'utilisation de la position et de l'alignement connus pour effectuer des corrections lorsque ledit plan sert de plan de référence. Plus précisément, l'invention concerne un procédé et un système pour déterminer l'angle d'inclinaison d'une surface plane par rapport à un faisceau laser, l'angle d'inclinaison ainsi déterminé servant à calculer un facteur de correction à appliquer au faisceau laser. En résumé, le procédé et le système permettent en fin de compte de calculer un facteur de correction, z-offset, que l'on applique lorsque l'on utilise le faisceau laser dans une procédure.
